Level of threshold weed density does not affect the long-term …
May 1, 1997 · It is shown that long-term application of thresholds results in a control frequency that is independent of threshold level, and in aperiodic dynamics of the weed population which may cause …
Dynamics of weed populations : spatial pattern formation and ...
The dynamics of a weed population subjected to such a 'threshold control programme' is characterized by aperiodic (quasi-periodic or chaotic) cycles, whereas the long-term herbicide use does not depend …
However, because most weed populations generate effects that carry over to following years, an eco-nomically-defined action threshold that deals solely with impact in the current sea-son is not suited to …
of threshold management on weed population dynamics. Such economic optimum thresholds are calculated using population-dynamics models which require detailed information about weed …
A Computable Economic Threshold Model for Weeds in Field Crops …
It is shown that long-term application of thresholds results in a control frequency that is independent of threshold level, and in aperiodic dynamics of the weed population which may cause uncertainty …
Weed Population Dynamics | Agronomy | MDPI
In this context, understanding the population dynamics of weeds is fundamental to our ability to manage and predict their spatial/temporal evolution, especially in the light of climate change, integrated weed …
optimal over a number of seasons? Wallinga and van Oijen, writing in the current issue of Crop Protection', show in fact that the choice of threshold level does not affect the long term
